Title: Composite games station with seat and shelf
Inventor: LOWN TERENCE GRAHAM
IPC: A47B83/02
Filed: 1994-04-06
Abstract: A games station, e.g. for carrying a VDU and associated controls, includes a seat 9, and a shelf 12, spaced from each other and joined by a pair of side walls 3, 4 and it may also include a foot rest 2. The distance between the seat, the front shelf and/or the foot rest may be adjustable so as to accommodate users of different size. The component parts of the games station are flat and are connected by slotted joints. Thus the games station can be transported or sold as a flat package kit which can be assembled, preferably without the use of tools, for display or use. The flat component parts may be cut from wood, reinforced card, hardboard, chipboard or composite board provided adequate rigidity is achieved. In general the load bearing parts, particularly the seat and foot rest, will be of greater rigidity than the other parts. The rear section of the games station may be hingeably mounted on the rest of the station (Fig. 4) so that the space taken up by the station may be reduced when not in use. <IMAGE>

Patent GB-2283136-A (GB)
Title: Electric converter circuits
Inventor: CORNES NIGEL WILLIAM
IPC: H05B41/34
Filed: 1994-10-21
Abstract: Current flow in an inductor 7 from a DC-voltage source 4, 5 is switched on and off by a series-connected controlled switch such as FET 8 under control of a latch circuit 10. The circuit 10 switches the FET 8 off in response to the attainment of a predetermined voltage across a resistance 9 in the series circuit, and switches the FET 8 on again in response to individual pulses of a constant-frequency pulse generator 14. Constant power output of the circuit to power a xenon tube 1 for a flashing warning beacon is derived from a capacitor 6 that is charged via a diode 13 from the current-backswing of the inductor 7. The latch circuit 10 may alternatively (Figure 3) be switched off from the voltage across a capacitor (24) in a resistance-capacitance circuit connected in parallel with the series FET 8 and inductor 7, a switch device (26) that shunts the capacitor (24) being operated in unison with the switching of the latch circuit 10, to discharge the capacitor 24 in the intervals between conduction of the FET 8. <IMAGE>

Title: Fuel metering system
Inventor: DYER GERALD P
IPC: F02C7/228
Filed: 1994-12-12
Abstract: The system comprises a pilot coaxial metering and pressure regulating valve (20) being coupled between a primary fuel inlet line (14) and the first and second sets of pilot nozzles (78, 80), and a main coaxial metering and pressure regulating valve (20') being coupled between the primary fuel inlet line (14) and the set of main fuel nozzles (98). A substantially constant pressure drop across each valve (20, 20') is maintained, the valve (20, 20') including a controlled metering window (50, 50') to precisely meter the fuel flow through the valve (20, 20') and to the respective sets of fuel nozzles (78, 80, 98). A control pressure regulating valve (120) maintains a minimum pressure differential between the fuel inlet line (14) and the downstream sides of the valves (20, 20'), and directs excess fuel from a fuel pump (12) into a return line (126). A minimum fuel pressure is maintained by a minimum pressure and shut-off valve (68, 68') coupled between each coaxial motoring and pressure regulating valve (20, 20') and the respective fuel nozzles (78, 80, 98). <IMAGE>

Title: Control apparatus for internal combustion engine with exhaust gas recirculation
Inventor: ISOBE DAIJI
IPC: F02M25/07
Filed: 1995-06-19
Abstract: In a mechanical type EGR apparatus, an EGR valve 11 receives a negative pressure from a port near a throttle valve 5 and opens/closes an EGR bath 10 in response to the negative pressure. A negative pressure control valve 20 is operated in response to an exhaust gas pressure to control a diaphragm back pressure to be introduced into the EGR valve. A CPU 32 calculates a control amount of an idling valve 7 in order to obtain an optimum EGR ratio characteristic, depending upon engine operation conditions, and drives the valve 7 based on this control amount. The negative pressure around the throttle valve is changed when the valve 7 is opened/closed and a portion of air into the engine flows through a bypass path, so that the diaphragm back pressure into the EGR valve is controlled to a desired value. <IMAGE>

Title: Hotplate control circuit providing reduced warm-up time
Inventor: BRINDLEY JOHN
IPC: H05B3/74
Filed: 1995-12-09
Abstract: If a heat-setting selector 6 is set to a desired setting at a time when a temperature detector 1 senses that the hotplate is cool, a control circuit 8 causes the hotplate heating element 2 or elements to be energised for a predetermined time in a manner to achieve a fast warm-up. The predetermined time may increase as the selected heat setting increases. If the element 2 is normally duty cycle controlled to achieve the required heat setting, then the element 2 is energised continuously for the predetermined period. If the desired heat setting is achieved by programmed control of one or more of a plurality of heating elements (10,11,12, Fig.2A), then one or more of the heating elements are turned on so that the total energy output during the predetermined period is greater than the programmed output for the selected heat setting. The detector 1 may have a first set of contacts which are used to detect when the hotplate is cool, and are also used to operate a neon indicator 9 to advise a user that the hotplate is still hot, and a second set of contacts which operate at the maximum safe working temperature.

Title: Attaching a chip to a circuit board using flexible pillars
Inventor: DRAKE JEREMY JOHN EDWARD
IPC: H05K3/34
Filed: 1997-05-07
Abstract: A flip chip (20)is soldered (21) to an array of flexible pillars (18) of compliant dielectric material on a circuit board (10). Each pillar has an electrically conductive core electrically coupled to the circuit board. The pillars absorb movement due to differences in the coefficient of thermal expansion of the chip and board, and hence reduce the possibility of fatigue failure of the solder joint. The pillars are manufactured by forming a layer of compliant dielectric material on the circuit board, forming blind holes in the layer, filling the holes with electrically conductive material overlapping the edges of the holes, and then laser ablating to remove the compliant dielectric material except where protected by the electrically conductive material.
